5. IMPLEMENTATION AND MAINTENANCE • A. SYSTEM IMPLEMENTATION • Introduction • System Implementation is the process of converting the physical system specification into working and reliable software and hardware document the work that has been done and provide help for current as working computer code by the programming team. • Depending on the size and complexity of the system, coding can be involved, intensive activity. • Once coding has begun, the testing process can begin and proceed in parallel. As each program module is produced, it can be tested individually, then as part of a larger program, and then as part of a larger system. • Although testing is done during implementation, we must begin planning for testing earlier in the project. • Planning involves determining what needs to be tested and collecting test data. This is often done during the analysis phase because testing requirements are related to system requirements. bcanepaltu.com
5. IMPLEMENTATION AND MAINTENANCE • A. SYSTEM IMPLEMENTATION • Introduction • Installation is the process during which the current system is replaced by the new system. This includes conversion of existing data, software, documentation, and work procedures to those consistent with the new system. • Although the process of documentation proceeds throughout the life cycle, it receives, formal attention during the implementation phase because the end of implementation largely marks the end of the analysis team’s involvement in systems development. • Larger organizations also tend to provide training and support to computer users throughout the organization. Some of the training and support is very specific to particular application systems, whereas the rest is general to particular operating systems or off-the-shell so bcanepaltu.com ftware packages.
